Unlike tcm_vhost_evt requests, tcm_vhost_cmd requests are passed to the
target core system, we can not make sure all the pending requests will
be finished by flushing the virt queue.

In this patch, we do refcount for every tcm_vhost_cmd requests to make
vhost_scsi_flush() wait for all the pending requests issued before the
flush operation to be finished.

This is useful when we call vhost_scsi_clear_endpoint() to stop
tcm_vhost. No new requests will be passed to target core system because
we clear the endpoint by setting vs_tpg to NULL. And we wait for all the
old requests. These guarantee no requests will be leaked and existing
requests will be completed.

Merge branch 'for-next-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending into vhost-net-next

Jeff Kirsher says:

====================
This series contains updates to e1000e, igb and ixgbe.

There are 2 patches in this series which could be applied to net,
but since Linus is so very close to releasing 3.9, I do not think
it prudent to try and push these into net at this time.  I have CC'd
stable on these patches so that they can queue them up as soon as
3.9 gets released.

The 2 patches are:
  e1000e: fix numeric overflow in phc settime method
  ixgbe: fix EICR write in ixgbe_msix_other

Richard provides a fix for e1000e by using a helper function from time.h
to resolve a unintended overflow in the PTP settime function.

Bruce provides a fix to wait for NAPI to be done with the current context
after disabling interrupts and then disable NAPI when the interface
is going down.  This fixes a possible "unable to handle kernel paging
request" panic in net-next.

Andi Kleen provides a patch for igb to use mdelay instead of udelay
when we needed 100000us.

Jacob provides a fix for ixgbe to simply mask the lower 16bits off so that
ixgbe_msix_other does not write them in the EICR, which causes them to
remain high and be properly handled by the clean_rings interrupt routine
as normal.

Emil cleans up the logic in ixgbe_setup_loopback_test() to only access
registers applicable to the MAC type.  In addition, removes majority
of the AUTOC register reads by using a cached value instead to avoid
writing corrupted values to AUTOC due to bad FW.  Emil also add support
for disabling link during boot time.  Lastly, he provides a patch which
adds the MAC type to the version in ethtool_regs which will make it
easier to check the MAC type when dumping registers with ethtool.

There is a separate ethtool tool patch which is dependent upon Emil's
last patch of the series to add the MAC type to the version in
ethtool_regs, which will be sent separately.

Previously, the ixgbe_msix_other was writing the full 32bits of the set
interrupts, instead of only the ones which the ixgbe_msix_other is
handling. This resulted in a loss of performance when the X540's PPS feature is
enabled due to sometimes clearing queue interrupts which resulted in the driver
not getting the interrupt for cleaning the q_vector rings often enough. The fix
is to simply mask the lower 16bits off so that this handler does not write them
in the EICR, which causes them to remain high and be properly handled by the
clean_rings interrupt routine as normal.

	vxlan: generalize forwarding tables

relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr().
This allows users to add multicast addresses using the fdb API.  However,
the check in rtnl_fdb_del() still uses a more strict
is_valid_ether_addr() which rejects multicast addresses.  Thus it
is possible to add an fdb that can not be later removed.

During high throughput it is likely that we receive both: an RX and TX
interrupt. The normal behaviour is that once we enter the ISR the
interrupts are disabled in the IRQ chip and so the ISR is invoked only
once and the interrupt line is disabled once. It will be re-enabled
after napi completes.
With threaded interrupts on the other hand the interrupt the interrupt
is disabled immediately and the ISR is marked for "later". By having TX
and RX interrupt marked pending we invoke them both and disable the
interrupt line twice. The napi callback is still executed once and so
after it completes we remain with interrupts disabled.

The initial patch simply removed the cpsw_{enable|disable}_irq() calls
and it worked well on my AM335X ES1.0 (beagle bone). On ES2.0 (beagle
bone black) it caused an never ending interrupt (even after the mask via
cpsw_intr_disable()) according to Mugunthan V N. Since I don't have the
ES2.0 and no idea what is going on this patch tracks the state of the
irq_disable() call and execute it only when not yet done.
The book keeping is done on the first struct since with dual_emac we can
have two of those and only one interrupt line.

- Use the above also on the other ndev in case of dual mac
- Free data.slave_data. The name of the strucre makes it look like

In case that we run into OOM during the allocation of the new rx-skb we
don't get one and we have one skb less than we used to have. If this
continues to happen then we end up with no rx-skbs at all.
This patch changes the following:
- if we fail to allocate the new skb, then we treat the currently
  completed skb as the new one and so drop the currently received data.
- instead of testing multiple times if the device is gone we rely one
  the status field which is set to -ENOSYS in case the channel is going
  down and incomplete requests are purged.
  cpdma_chan_stop() removes most of the packages with -ENOSYS. The
  currently active packet which is removed has the "tear down" bit set.
  So if that bit is set, we send ENOSYS as well otherwise we pass the
  status bits which are required to figure out which of the two possible
  just finished.

netif_running() reports false before the ->ndo_stop() callback is
called. That means if one executes "ifconfig down" and the system
receives an interrupt before the interrupt source has been disabled we
hang for always for two reasons:
- we never disable the interrupt source because devices claim to be
  already inactive and don't feel responsible.
- since the ISR always reports IRQ_HANDLED the line is never deactivated
  because it looks like the ISR feels responsible.

This patch changes the logic in the ISR a little:
- If none of the status registers reports an active source (RX or TX,
  misc is ignored because it is not actived) we leave with IRQ_NONE.
- the interrupt is deactivated
- The first active network device is taken and napi is scheduled. If
  none are active (a small race window between ndo_down() and the
  interrupt the) then we leave and should not come back because the
  source is off.
  There is no need to schedule the second NAPI because both share the
  same dma queue.

if during "ifconfig up" we run out of mem we continue regardless how
many skbs we got. In worst case we have zero RX skbs and can't ever
receive further packets since the RX skbs are never reallocated. If
cpdma_chan_submit() fails we even leak the skb.
This patch changes the behavior here:
If we fail to allocate an skb during bring up we don't continue and
report that error. Same goes for errors from cpdma_chan_submit().
While here I changed to __netdev_alloc_skb_ip_align() so GFP_KERNEL can
